问题描述
我做的第一次工作，但第二次打破了
len = Convert.ToDouble（Console.ReadLine（））;
它说我有一个未处理的系统格式异常。帮助！
使用System;
使用System.Text;

rect.assign（len，wide）;
控制台。写（Rectangle length =" + rect.getLength（）+ \ n"）;
Console.Write（" width =" + rect.getWidth（）+" \ n"）;
Console.Write（" area =" + rect.getArea（）+" \ n"）;
Console.Write（\ n你要继续吗？输入1继续，2输入

完成此操作）;}

}
My do while works the first time but the second time it breaks at the
len = Convert.ToDouble(Console.ReadLine());
It says that I have an unhandled System format exception. Help!

推荐答案
从外观上看，问题出在你的行中：
any = Console .Read（）;
而不是只接受一个特征呃，它迫使你按回车键，
，我怀疑它是由下一个ReadLine（）部分处理的，当它看起来像是b $ b。一个选项是将any = Console.Read（）更改为any =
Console.ReadLine（），它将以相同的方式工作，只有它不会打破
秒时间过去了。

" Rachel"写道：
From the looks of it, the problem lies in your line:
any = Console.Read();
Rather than accept only a single character, it forces you to press enter,
which I suspect is being partially handled by the next ReadLine() when it
looks. One option is to change any = Console.Read() to any =
Console.ReadLine() which would work the same way, only it would not break the
second time through.
